What have the Foxsat and BD been connected to before? - although as far as I'm aware you can't disable the sound from them over HDMI?.

I'm presuming you've tried turning the volume up? - as the volume is probably independent of the other inputs (and could be turned right down).
I'm also presuming you're using just the TV, and no external sound system?.

The Foxsat and BD were connected to a Yamaha soundbar which is disconnected at the moment. You are right I am using, or trying to use, only TV sound.

Thanks for that but yes I do get sound from internal tuner and also Sky box but that is from scart.

In that case I suspect that the audio settings are screwed somewhere.

Was the soundbar one of those clever ones that creates virtual rear speakers to give the impression you've got a full 5.1 surround system by any chance? If so then it could well have been able to deal with a multi channel output from the Humax/Sony. The TV might only be able to deal with plain stereo. So the output format on those two would be the first thing to check.
